Application filed November 13, 1917. VSerial No. 201,759.

To all whom t may concern:

Be it known that I, HOWARD M DUDLEL a citizen of the United States, residing in the city of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented certain new and useful Improvements in Dyeing-Machines, of which the following is a full, clear, and exact specification.

My invention relates to devices suitable for the dyeing of textile fibers and refers particularly to devices suitable for the dyeings vof cops, spools and other similar forms of textile fibers in which the fiber is wound upon hollow central members.

One object of my invention is a device suitable for the dyeing of a number of wound ber forms by the passage of a liquid therethrough.

Another object of my invention is a device in which a number of wound fiber forms may be compressed and treated evenly and uniformly by a liquid.

Another object of my invention is a device containing a series of liber chambers suitable for holding a number of wound ber forms and having means whereby a liquid .may be passed evenly through the fiber.

Another object of my invention is a device suitable for the dyeing of wound liber forms in which'tlie condition of the dyeing treatment may be determined without opening the dyeing receptacle or interrupting the treatment therein.

rIhese and other objects of my invention will be evident upon a consideration of my speeilication and accompanying drawings.

In the dyeing of wound liber forms, such as cops, spools and similar forms, iii which the ber is wound upon imperforate hollow members, it is essential that the fiber be maintained in its original position upon the wound form, in order that it may be readily unwound therefrom. As these wound fiber forms do not contain a great length of fiber, a numbermust be treatedv simultaneously, and tliedevice must allow the fiber to be paclcedin a uniform mass. Further, the liquid must be passed through the entire liber mass uniformly and equally.

Fig. 7 is an enlarged vertical cross-section of a series of wide .fiber forms mounted upon a core and ready for insertion into a liber chamber. f

Fig. 8 is a vertical cross-sectionvof the testing device.

In the particular form of my device shown in the accompanying drawings, a receptacle is formedby the shell 10, the top member 11 and the bottom member 12 within the shell 10 is a series of fiber chambers 13, 13, 13. The upper portion of the shell 10 has an an'-` nular flange 14. A removable spider member 15 is capable of abutment upon an offset in the ange 14, the screw bolts 16, 16, 16 reniovably attaching the spider 15 tothe shell 10. In alinement with the center of each fiber chamber 13 is a screw bolt17 meshing with threads in the spider 15. Revoluble upon the bolt 17 is a member 18 having downwardly extended arms 19, 19, capable of abutment upon the annularv foraminous plate 20, the member 20 being held from n slidable movementv along the bolt 17 by the set screw 21 and the shoulder 22 of the bolt 17. TWithin eaclifiber chamber `13.isv a removable cylindricalelongated core 23 shown particularly in Fig'. 7, the upper end 211 of which is conical shaped and has an `opening 25 for the'insertion of the hook 26 for removing tlie core. .'Ihe lower end 27 of the core `23 is of conical shape with the shoulder 28. Capable of abutment upon the 'shoulder 28 of each core 23 is-an annular foraminous plate 29 slidable within the liber charnber`13.I Below the shell 10 is a spider 30, shown particularly in Fig. 3, this spider 30 beinginwardly attached tothe flange 31-of the shell 10 by means of screw bolts 32, 32 passing through openings in the flange 3l and meshing in threads in the spider' 30. The spider 30 carries a series of indented members 33, 33, the indents of which are capable of receiving the lower extremities of the cones 27, 27. Each liber chamber 13 is connected with a testing device, shown in Fig. 8, the interior arrangement of which is similar and proportionate to the interior arrangement of the larger fiber chamber, similar parts being designated by prime members. The member 34 is threaded with the shell 10 and conical end of the core 27 lits in an indent in the member 35 carried bythe member 34. rIhe member 36 is threaded with the shell 10 and abuts upon the foraminous plate 20. The lower end of the shell 10 is removably attached to the pipe 37, carrying the valve 38, by means of the bushing 39. The pipe 37 is threaded into the conduit 40 which opens into the chamber 41 ofthe bottom 12. The upper end of the shell 10 is removably attached to the pipe 42 carrying the valve 43, by -means of the bushing 44. The pipe 42 is threaded into the conduit 45 which opens above the foraminous plate 20.

The foraminous plates 20 and 29 are similar in construction and comprise a series of concentric annular members 47, 47, connected by the member 48, 48. 'The annular members 47, 47 comprise a series of triangular members 49, 49 between which are the truncated triangular members 50, 50.

The top member 11 carries a ring 51 to facilitate the removal thereof, and has a contracted cylindrical portion 52 which is removably attached to the pipe 53 by means of the coupling 54. The pipe 53 carries the valve 55 and is connected to the discharge chamber of the pump 56. The bottom member 12 has a contracted cylindrical member 57 threaded to the pipe 58, carrying the valve 59 and connected to the discharge chamber of the pump 56. The pipes 53 and 58 are connected by the pipe 60 carrying the valves 61 and 62, the pipe 60 being connected to the pipe 63 opening into the upper portion of the reserve tank 64'. The bottom of the reserve tank 64 is connected to the receiving chamber of the pump 56 by means of the pipe 65 carrying the valve 66. The receiving chamber of the'pumpj 56 is also :connected to a dissolving tank, not shown,

by means of the pipe 67 carrying the valve 68. A pipe 69 carrying a valve 70 connects the receiving chamber of the pump 56 with a source of fresh water supply. A drip pipe 71 carrying the valve 72, opens into the bottom` chamber 41.

4The fiber 100 is wound upon a series of hollow cylindrical members 7 3, 73 capable of abutment upon, and slidable over the cores 23, 23, as shown in Fig. 7. These members 73, 7 3 are composed advantageously of thin metal and have notched or indentedends 74, 74, the extended ends being capable of slidably entering the indents of the adjacent member.

Assuming that the device and its contents are as shown in F ig. 1, and the dyeing completed, the operation of the device is as follows:

The member 52 is disconnected from the pipe 53 by means of the bushing 54. The top 11 is then disconnected from the flange 14, by means of the screw bolts 75, 75 which pass through openings in the flange 76 of the top 11 and thread with threaded openings in the flange 14. The top 11 is then removed, and the screw bolt 16 is removed thus allowing the removal of the spider 15 with its described connected members. Each core 23 is then removed from its fiber chamber, carrying with it the dyed liber. The wound fiber forms are then removed from around the core 23. A foraminous plate 29 is then placed around the core 23 and new ber forms 100, 100 are also placed around the core 23, care being observed to see that the indents and extensions on the ends of the holders 73 will mesh with one another. The core, with the fiber thereon, is then placed inv a fiber chamber, the foraminous plate 20 placed thereon, the spider 15 with its attached members, placed upon the shoulder of the flange 14 and the screw bolt 16 employed to attach the spider 15 with the shell 10. The top 11 is lowered and the member 52 and the pipe 53 attached to each other by the coupling 54. The foraminous plates 20, 20 are forced downwardly by turningv the bolts 17, 17 ,Y thus forcing downwardl7 the members 18, 18 and the arms 19, 19 abutting upon the plates 20, 20. The screw bolts 75, 75 are then inserted and screwed inwardly thus attaching the top 11 to the flange 14. At the same time, the foraminous plates 29,V` 29 are pressed inwardly by turning the screw bolts 32, 32, thus bringing the spider 30 inwardly and forcing the core 23 upwardly.

It will thus be seen that the fiber Vis compressed from both ends of the mass, thus producing a mass of equal consistency throughout. The testing device is removed from connection with the pipes l37 and 42 by unscrewing the bushings 39 and 44 and the shell 10 withdrawn and loaded with wound fiber forms 100, 100 between the foraminous plates 20 and 29 and compressed by means of the members 36 and 34. The testing device is then replaced and con nected with the pipes 37 and42.Y

All ofthe fiber chambers being thus loaded with wound' fiberforms, all of the valves are closed with the exception yof valves 68, 59, 3 8, 43 and 61,.and the pump started. Dye liquid thus passes from the dissolving tank, not shown, through the pipe 67, the pump 56, the pipe 58, the chamber 4:1, the iioraminous plates 29, 29, the bers 100, 100, the ioraminous plates 20, 20, the chambers Li6 and 80, and the pipes 53, 60 and 63 into the reserve tank Gel. l/Vhen sufficient dye has been injected into the device, the valve 68 is closed and 66 opened, thus allowing a continuous circulation of the liquid through the device. Lhe liquid, at the same time, passes through the conduit 4:0, pipe 37, oraminous plate 29, the ber 100', 100', plate 20', pipe 42 and conduit 45. V7 hen it is desired to reverse the ow or" the liquid, the valves 59 and 61 are closed and valves 55 and 62 opened. Fresh water for washing purposes may be admitted through the pipe 69, after the dye liquid has been drained off through the pipe 71. At any time desired, the condition of the ber in the larger ber chambers may be judged by closing valves 38 and 43, removing the testing device and examining its contents, the dyeing operation still continuing.

t is evident that by the combined compression oit the ber from both ends, a more uniform mass is produced than by compression from one end alone, that the projections upon the foraminous plates will allow oi a. freer passage of the liquid at the ends of the ber mass and that the reverse ow of the liquid will cause even penetration of the mass.

I do not limit myself to the particular size, number, shape or arrangements of parts as described, all of which may be varied without going beyond the scope of my invention as described and claimed.

What I claim is l. In a dyeing machine, in combination, a receptacle, a series of ber chambers within the receptacle, an imperforate core within each ber chamber, a series oiE imperforate hollow members capable of slidable movement over each core and capable of having ber wound thereon, means at both ends of l each ber chamber for compressing the ber and means for forcing a liquid through the compressed ber mass.
